A normal distribution of 10 and a standard of 1. What is the probability of selecting a number that is at most 9?

Answers

Answer 1

Answer:

0.15866

Step-by-step explanation:

The term at most 9 means = less than or equal to 9

This represented as x ≤ 9

We solve using the z score formula

z = (x-μ)/σ, where

x is the raw score = ≤ 9

μ is the population mean = 10

σ is the population standard deviation = 1

z = 9 - 10/1

z = -1

Probability value from Z-Table:

P(x ≤ 9) = 0.15866

Therefore, the probability of selecting a number that is at most 9 is 0.15866

A square photo has a side length of 0.17 foot. The photo is enlarged by doubling the dimensions. Then it is enlarged again by tripling the new dimensions.

Answers

Calculate the side length of the enlarged picture

Answer:

Hence, final picture will have a side length of 1.02 foot

Step-by-step explanation:

Side length of square photo, s = 0.17

Original dimension = (0.17 by 0.17)

Enlarged photo = double the original dimension:

2 * (0.17 * 0.17)

(0.34 * 0.34)

Second enlargement = Tripling the new dimension:

3 * (0.34 * 0.34)

(1.02 * 1.02)

Hence, final enlarged dimension = (1.02 * 1.02)

Hence, final picture will have a side length of 1.02 foot

Tam thinking of two numbers. The first number is 1 more

The sum of the two numbers is 25.
What are my two numbers?

Answers

Answer:

First number is x

Second number is y

x = 2y + 1

x + y = 25

(2y + 1) + y = 25

y=24/3

y = 8

x = 2(8) + 1

x = 16+1

x=17
